Guzmania plant named ‘DURAPRI’

ABSTRACT

A new and distinct variety of Guzmania plant named ‘DURAPRI’ which is characterized by the combination of a flattened globular plant profile with foliage arranged in an attractive rosette, relatively short foliage with a dark green upper surface and a greyed-purple lower surface, an inflorescence with a rounded profile, born on a short peduncle, an inflorescence with red floral bracts which are tipped white, and the stability of all characteristics from generation to generation.

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Guzmania lingulata.

Variety denomination: The inventive variety of Guzmania disclosed herein has been given the variety denomination ‘DURAPRI’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2017/1807, filed Jul. 18, 2017, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Guzmania variety ‘DURAPRI’ is a seedling selection which resulted from a controlled pollination breeding program. In July of 2007, the inventor performed the controlled cross-pollination of Guzmania lingulata ‘Fortuna’ (not patented), the seed parent, and an unnamed dwarfed seedling progeny of Guzmania lingulata ‘El Cope’ (not patented), the pollen parent, at a commercial greenhouse in Alajuela, Costa Rica. Those skilled in the art recognize that Guzmania seed can be difficult to germinate. Therefore, in November of 2007, the seed that resulted from the cross of July 2007 in Alajuela, Costa Rica were shipped by the inventor to a tissue culture laboratory in Evergem, Belgium for in vitro seed germination in order to increase the germination rate. At the direction of the inventor, the resulting seedlings were grown for 6 months to evaluate plant vigor and then shipped back to Alajuela, Costa Rica for further evaluation by the inventor. In November of 2008, the inventor selected one seedling for commercial production due to its unique growth habit and flower characteristics. This new and distinctive cultivar was given the name ‘DURAPRI’.

Asexual Reproduction: ‘DURAPRI’ was first asexually propagated by meristematic tissue culture in January of 2014 at a commercial laboratory in Evergem, Belgium and has since been asexually propagated through 3 additional generations. Through subsequent generations, the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘DURAPRI’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DURAPRI’. These characteristics, in combination, distinguish ‘DURAPRI’ as a new and distinct Guzmania cultivar:

-   -   1. Guzmania ‘DURAPRI’ exhibits a flattened globular plant         profile with foliage arranged in an attractive rosette; and     -   2. Guzmania ‘DURAPRI’ exhibits relatively short foliage with a         dark green upper surface and a greyed-purple lower surface; and     -   3. Guzmania ‘DURAPRI’ exhibits an inflorescence with a rounded         profile, born on a short peduncle; and     -   4. Guzmania ‘DURAPRI’ exhibits an inflorescence with red floral         bracts which are tipped white.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in June of 2017 describe averages from a sample set of six specimens of 12 month-old ‘DURAPRI’ plants grown in 8 cm nursery pots at a commercial greenhouse in Evergem, Belgium. Plants were grown under light maximum light levels of approximately 12,000 lux. Plants were maintained with a fertigation program and regularly watered with overhead irrigation. No chemical pest measures were taken.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘DURAPRI’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
